| 内容記述 | Quasi-static behavior of a poroelastic circular cylinder subjected to constant strain-rate, axial, compression was analyzed within the framework of the continuum mechanics of fluid-saturated, linear, poroelastic materials. The solutions obtained in the Laplace space were numerically inversed into the time domain. The results were illustrated in the form of curves for a wide range of drained Poisson’s ratio (from positive to negative). It was found that, although the axial strain increases linearly with respect to time, all other strains, pore fluid pressure and all stresses do not; especially, in the case of the negative Poisson’s ratio, the tangential strain becomes tensile immediately after loading and reverses its sign after a while; thereafter the compressive strain grows up to infinity. The pore fluid pressure and the tangential stress approach a steady state (constant) value after experiencing their transient process. Apparent stress-strain curves are nonlinear due to the pore fluid diffusion, with the more nonlinear for the smaller Poisson’s ratio, especially for the negative ratio. |
